Featuring the world’s first full-frame (35-mm) stacked sensor with built-in memory, the α9 is a professional-grade mirrorless SLR that takes high-speed performance into a new dimension. In addition to snapping continuous shots with AF/AE tracking at 20 fps, the camera also eliminates viewfinder blackout. All that functionality comes in a small, lightweight package, giving professional photographers the operability and reliability they need in a convenient setup. Big SLRs used to be the norm in field photography—but the α9, with its range and expressive potential, redefines that assumption.
